The woodcutter always wanted his son to go to school, but they didn't have enough money, and after a few years he had to come home.
During a lunch break, instead of resting, he defied his father and went wandering through the forest, where he heard a voice saying it was trapped at the bottom of the tree.
There he saw a bottle, but when he opened it a giant demon sprang out and said it would break his neck and kill him.
The young woodcutter then challenged the demon spirit, saying that it did not have the ability to get back in the bottle.
The demon, shocked, began begging the woodcutter's son to open the bottle again, but he refused unless the spirit promised to benefit the boy.
